IMPROVEMENT IN MACHINES FOR COMPRESSING SOLE-FASTENINGS.

Specication forming part of Letters Patent No. 159,859, dated February 16, 1875 application filed December 17, 1874.

CASE B.

To all whom it may concern:

Be it known that I, BENJAMIN F. STURTE- VANT, of Boston, in the countyof Suffolk and State of Massachusetts, have invented an Improved Machine for Oompressing Sole-Fastenings, of which the following is a specification:

My improvement relates to a machine for compressing fastenings for uniting soles to boots and shoes; and consists in a pair or set of compressors or jaws, for consolidating the peg ribbon or strip, and heated by the application of flame to the material forming the compressors; also, in the combination, with compressing-jaws, of a rotating peg-strip-moving mechanism adapted to move the material between the jaws, substantially as described; also, in the combination, with compressors or jaws for consolidating peg-wood, of mechanism for moving the peg-strip, and for winding it; also, in compressors or jaws, constructed Substantially as hereinafter described, and in other features specified and claimed.

The ribbon or strip of peg-wood is cut from or around the log in any well-known way; and I prefer that such ribbon be cut so as to present, in cross-section. substantially the form shown in Figs. Gand 7; and when compressed by the compressing-jaws they will assume substantially the shape represented in Figs. 8 and 9, the degree of compression being about as represented between the dotted lines and full lines, and the points are formed by compressing the material hardest at one edge, substantially as set forth in an application tiled at the Patent Ofce concurrently with this, and another application describes my new method or process for making the said new article of peg-ribbon or peg-strip.

Pegs compressed by this machine are compacted and consolidated, and they remain in this compacted condition until a gain swollen by the action oi' moisture. The heated jaws liberate and turn into steam the remaining moisture of the wood, and the glutinous matter, warmed and started, acts to hold the bers of the wood in their consolidated-position. The compressors compress the same portion of the strip many times in passing between them,

and these repeated actions of the compressors harden and compact, but do not destroy, the grain of the wood.

Figure l is a top view of my improved machine. Fig. 2 is a longitudinal section. Fig. 3 is an enlarged section of the compressors or jaws for compressing the peg strip or ribbon. Fig. 4 is an end view thereof. Fig. 5 is a longitudinal section of the face of the compressors or jaws; and Figs. 6,7, 8, and 9 represent cross-sections of peg strips or ribbons, both before and after being compressed.

A represents the bed-piece of the machine,

having rising therefrom lugs a a, which form bearings for a cross-shaft, b, having a cam, c, or other suitable connection, adapted to move the rockin g arm or lever d, having its fulcrum on shaft f. The lower or stationary member e of the compressors or jaws Jforms part of, or is connected with, the bed-piece A, and the upper member el, in this instance, is connected with, or forms part of, the rocking arm d. These compressors or jaws are represented enlarged in Fig. 3; their faces are, in their width, substantially parallel, but in the direction ot' their length they are somewhat inclined, as in Fig. 5, being somewhat farther apart at their receiving end m than at their discharging end y. One of the members e el is to have a lip or ledge; in this instance the stationary member c has the lip or ledge e3 formed or connected with it, against which rests that edge of the ribbon peg wood or blank which is to serve for the heads of the pegs, and the opposite sides of the compressors are provided with bevels or inclines more or less acute, and adapted to bear on that edge of the ribbon or peg-wood strip which is to serve for the points of the pegs. The stationary member e has at its inner face, and beyond its beveled portion, another lip or flange, r, which acts as a guide for that edge of the peg-strippassing near it. Ihe shaft b has a fly-wheel, b', and is driven by power, or otherwise, and a crank, t', thereon is connected, by link il, with a pawl, t2, adapted to en gage and move a toothed ratchet, h2, secured to a shaft, h, provided with bevel-wheels h1 h1 that engage bevel-wheels g3 g3 on the ends of shafts g1 g4 of the pegstrip moving mechanism, said mechanism acting to give the ribbon peg-strip an intermitting feed or movement through between the compressors. The wheels gj are placed in pairs, those g acting to present the material, and the setj acting to take it away from the compressors. These rollers are in pairs, one of each pair being, preferably, hanged, to guide and contain the ribbon peg-blank, and the other rollers are adapted to bear on the material contained within the annular grooved space of the anged rollers. The upper and lower rollers of each set are connected together by means of toothed wheels g2 g2, and they all move at substantially the same speed.

Near the compressors is a pipe, kn, through which gas passes, issuing therefrom in the direction of the arrows Z l, and, iguiting, the iame is blown with force against the material forming the compressors by means of air forced through a pipe, m. The iialne acts to heat the compressors as hot as may be required to properly compress the pegstrip.

The ribbon peg-blank, sustained preferably on a reel, o, is led between the rollers g, and then between the faces of the compressors to and between the second set of rollers j, and then it is preferably wound again into a coil on a reel, o1. This reel o1 is mounted ou an arm, o3, connected with a shaft, 04, having a spiral or other spring arranged in connection with it, so that the reel has a tendency to press upward against a roller, o2, which bears on the material on the reel 01, and moves the reel about its axis, the roller o2 deriving motion from a train of gear-wheels, g2 s t. The edge ofthe ribbon peg-blank which is to form the heads of the pegs rests against the ledge or lip c3, and the edge which is to be compressed sufticiently to form the edge for the points of the pegs rests at the opposite side of the compressors. The upper member el, as it descends, rst strikes the ribbon of pegwood on that edge which is to forni the points. The beveled ends of the compressors, grasping and firmly compressing such edge, squeeze and consolidate it, forming a point-forming edge, substantially as set forth in another application filed concurrently with this, as before stated, andas shown in Figs. 8 and 9. These compressors close gradually ou the strip of peg-wood, and consolidate it laterally. rlhe head-formin g edge of the strip is forced firmly against the ledge c3, and substantially all the water and glutinous material in the strip is gradually stripped or forced toward the edge of the strip resting against e3, and when the compressors are closed the ribbon peg-blank is consolidated to any required degree.

The heated compressors act to set and hold the wood or fiber as compressed, and they iron or sear the surface and edges of the ribbon peg blank or strip.

This compressed pegstrip presents many.

advantages over ordinary peg-strips, such advantages being set forth, as before stated, in

another application, to which reference is made.

I do not, in this application, desire to limit myself` to jaws of the exact shape shown, for they may be variously modified as to the bevel of the faces, and they may be made adjustable on the parts A d, set-screws 't1 t2 being shown for that purpose, and the movable coInpressor may be actuated by any suitable devices, and have a vibrating or rectilinear motion.

In some instances I may use the rotary pegstrip-moving or feed rollers with unheated jaws, and with my heated jaws may use other well-known feeding devices common to sewing and other machines, instead of the rotating devices shown; or, instead of heating the jaws, I may heat the strip before it enters the jaws. For this purpose I provide, in advance of the compressors, a box or chamber, u, heated by steam passing through pipes u', or by gas issuing from pipe o1., as indicated by the arrow l', Fig. 1.

The peg-strip is designated by the letter w. The direction of the movement of the steam for heating the compressors is shown by arrows w. The journal-boxes of the shafts supporting the upper rollers g j are kept down by springs fr.
